Please. Of course any president could always do anything, and of course it’s always up to the prosecutor to make a case. Are you really claiming that the Supreme Court setting the precedent that presidents are exempt from criminal liability is not a change? Does the weight of that precedent not make prosecuting presidents vastly more difficult and, apparently, impossible in many important ways? Does that fact not make it much more likely that presidents will commit crimes? You may want that change, but there is no merit to the argument that this decision doesn’t change anything.
